How can I tell which XPNDR I have installed? I know the Trig TT2 pn is 000745-00-03, but what does that cross to. I just ordered the GPS-2020 and need to know if I have to replace the transponder as well.

The transponder itself has a label on it that says if it's a 261 or 262. There is not a way to tell from the SkyView screen.

So, I have to disassemble the airplane to figure this out? Dynon doesn't have listing of which Trig Part Number is which? Really!

The SV-XPNDR-261 is a (customized, OEM version) of the Trig TT22. The Trig part number for this is 00745-00-03
The SV-XPNDR-262 is a (customized, OEM version) of the Trig TT21. The Trig part number for this is 00675-00-03
Note that there are identifying stickers for BOTH Trig and Dynon on the transponder (on opposite sides of the case).
Also, you can check SETUP MENU > SYSTEM SETUP > SERIAL PORT SETUP > SERIAL PORT x SETUP (the one you used for the transponder). It will be set to either the SV-XPNDR-261, or SV-XPNDR-262. However, since the firmware of the two units is identical, it's possible to incorrectly set a physical SV-XPNDR-261 to an SV-XPNDR-262, and vice-versa, so that setting is not definitive as to which hardware is actually installed.

Don,
That is not true. They both use the same firmware so there's no way to mess one up by telling SkyView it's the wrong transponder.
What does (rarely) happen, is that the update process from the SkyView display can get interrupted (or other error) and the transponder doesn't get correctly updated. When that happens, the transponder can USUALLY get reprogrammed at Dynon Avionics using a special procedure (it rarely has to get sent back for a full repair other than an actual hardware failure).
